Ah! good point... -but we are pretty used to listening to repeated musical phrases - I mean, music is, by nature, built out of nested repetitions (opinion)` l think speech is much more immediate. In fact, a repetitious speech (I don't mean repetitive) is often hard to listen to, and we talk about someone 'droning on'. admittedly, some people say the sme about some music - especially process music. But I think if the music didn't change at all, we might begin to treat it as 'noise'. So I wonder if there is likely to emerge a stage where the repeated phrase 'comes out the other side' and gradually ceases to be musical any more? regards ppl >>> "Al Bregman" <al.bregman@xxxxxxxx> 13/12/2006 19:29 >>> Hi Peter, You wrote: "on repetition, there's no new semantic content, > and so semantic content slips down the priority list, allowing other > characteristics to move up in priority)," But with repetition, there is no new musical information either. Why doesn't the musical content slip down the priority list too?
